I tested that if I don't export CFLAGS, they do not show up in config.log,
if I export a value, I can reproduce your issue (or I can set a value that
does not break compilation).

I also confirmed that git grep mfpu did not show anything suspicious.

In general, builds that use CFLAGS are not supported.
